Sony KDF-E55A20 Lamp Shut Down with no blinking lights

Lamp shuts down then after about a minute it turns back on then after about a minute the cycle repeats. The audio cycles on a off with the lamp. The power lamp stays on with no blinking during the cycle. The lamp light has never come on. Solved the problem in the past buy pulling the lamp and vacuuming the screens but it has returned and vacuuming is no longer helping. TV is 2 1/2 years old with original bulb.

    Yep! I have the same problem with my KDF-E55A20. Watching the TV and the picture goes out, but the TV green light is still on. After less than a minute the picture goes back on. Several times, the problem repeated itself after a minute or so; other times it won't occur for 30 to 60 minutes. It is happening more and more now. I am in the market for a new TV for another room. Won't buy another Sony after hearing about all of these out of warranty problems. Luckily I have not had the yellow effect that many others mention. Not sure if it is a problem with this model.

If you TV is about 2 1/2 yr you probably need a new lamp they only last about 3 yrs. Mine popped one night and now picture comes in for about 1 min and goes out, I ordered a new lamp today they run $199. There is also a know issue with the thermal fuse. The part cost about $3 and if you know a lil about electronic you can replace it yourself

How do you replace the ballast on a kdf e55a20

to change a ballast board its a bit of work and a tear down to get it in there . but first lets review your problem .
its cycling off every 30 seconds . id suspect a defective lamp or a power supply problem since it sounds as if the ballast board does fire . that's assuming that you do see something come up on the screen when it attempts to start if a ballast has failed it usually will make a noise or the set would almost go into a shut down . also how many blinks and what order are the events happening ?

Strange situation, have you tried unplugging it for a few minutes and letting the TV cool. I have a older 2006 Sony SXRD rear projection and it takes forever to turn back on if you shut it off then turn it back on. Check this link and maybe its giving you a blinking code. Try counting the number of blinks. Hope this helps.

My sony kdf-60wf655 keeps shutting off on its own.what is the problem and can i fix it myself

If tv turns back on itself after shut down then it is weak lamp problem, replace lamp in tv to fix its problem.
Buy Sony original lamp for good picture in tv and replace it as it is user level repair and lamp replacement procedure is mentioned in related user manual.
If standby light start blinking after shut down, let me know how many times it blinks after three second pause to provide you info about possible cause of problem.

Sony KDF-E55A20 problem: picture goes intermittently black and no sound. Green light is still on. Just started to happen. Is increasing in frequency. Not sure if I hear the fan working or not.

Same thing happened to me. If you shut it right down and then start it back up do you get 5 red flashes? if so then what I did was replace the lamp as it was real old. This took care of it.

Hopefully it's still under warranty or you purchased an extended warranty. My concern is that it is either a power supply issue or a lamp ballast issue. If it has overheating in the past then there may be other issues going on.
Would suggest bringing it into a good trusted service shop.

Tv is shutting down then restarting.

How old is this TV, if its more then 2 years old and have not replaced lamp yet then its problem of weak lamp. Please replace its lamp and always purchase Sony original lamp for smooth TV function.
